Hi all, I am having a problem with GAIA, which attempts to launch "netscape" (a browser we no longer have installed). Here we are running the Starlink Hawaiki 64bit version (thus GAIA v4.4.0) in a Fedora 8 PC. The problem shows up when doing the following: Load some image in gaia Data-Servers -> Catalogs -> NED at CADC Then, in the new window, click on Search Click on any of the objects found, then "More Info" The error message is "Warning: couldn't start netscape: couldn't execute "netscape": no such file or directory. I was unable to find in GAIA itself an option to change the browser. However, I discovered that there exists a variable, HTX_BROWSER, which defines which browser to use (I set it to /usr/bin/firefox) Unfortunately, it does not work as expected: while now, on the main GAIA windows, Help -> About SkyCat indeed launches firefox, the problem with the catalog still remains. I tried a simple trick like "alias netscape /usr/bin/firefox", but with no success. Does anybody has a suggestion on how to fix this problem or some workaround? Thanks very much, Nicola --------------------------------------------------------------------------------------------- ADVERTENCIA: Sobre la privacidad y cumplimiento de la Ley de Protección de Datos, acceda a http://www.iac.es/disclaimer.php WARNING: For more information on privacy and fulfilment of the Law concerning the Protection of Data, consult http://www.iac.es/disclaimer.php?lang=en
